RUBBER HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 78 5,577, dated r h 21, 1905.

Application filed July 25,1903. Serial No. 166,971.

To (all whmn it nmty concern:

Be it known that I, AUGUSTE SANDFIELD, a citizen of the United States of America, residing at Swissvale, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in horseshoes; and the invention consists in constructing a horseshoe entirely of rubber whereby to produce a shoe of sufficient strength to protect the hoof and at the same time afford a soft tread to prevent shocks and jars liable to injure the animal.

Briefly described, the invention is a shoe made entirely of rubber, the toe and calks being integral with the body of the shoe, and the shoe is provided on its underneath face with projections, the lower points of which are on a line with the lower face of the calks and toe. The shoe-body is provided with openings to permit the ready insertion and driving of the nails which hold the shoe to the hoof, and I preferably construct the shoe-body with a flange to lie against the sides of the hoof, and thus cover the joint between the shoe-body and the hoof.

The above construction will be hereinafter described more fully in detail, and in describing the same reference will be had to the accompanying drawings, forming a part of this invention, and wherein like numerals of reference will be employed for designating like parts throughout the different views, in which Figure 1 is an inverted perspective view of my improved horseshoe. Fig. 2 is a crosssectional view showing the shoe in position on the hoof. Fig. 3 is a detail perspective view of a part of the shoe in modified form. Fig. I is a like view of another modification. Fig. 5 is a cross-sectional view of one side of the shoe.

To put my invention into. practice, I mold or otherwise form a shoe-body l of the desired shape-and size and which is provided with flat integral heel-calks 2 and flat integral toe-calks 3. This shoe-body is also pro vided at the front with an integral clip 4 and also has an integral flange 5, which extends around and covers the joint between the base of the hoof and the upper face of the shoe. The shoe is composed of rubber of a desirable consistency, and the body of the shoe is provided with holes 6, made only of a size to permit the entrance through the rubber body of the shanks of the nails 7, by means of which the shoe is fastened to the hoof 8. Made integral with the underneath face of the shoe are a series of projections, preferably of a substantially triangular form, as shown at 9 in Fig. l and Fig. 2, the lower points of these projections being substantially on a line with the lower face of the calks and the toe. I may vary the form of this projection, as shown at 10 in Fig. 3 or as'shown at 11 in Fig. 4, the same being integral with the shoe in any form of construction.

It will .be noted that the projections 9 on the lower face of the shoe are radially disposed with relation to the substantially circular contour of the shoe and that said projections are comparatively narrow, while the toe and heel calks are flat on their lower surfaces and of such width that they will be substantially rigid against lateral motion. The projections therefore form elastic tongues which will yield to the required degree to enable the shoe to rest firmly when brought down upon an unequal surface, whereas the flat toe and heel calks will form a sufliciently rigid bearing to enable the shoe to rest secure upon a fiat surface, such as a level road or a concrete roadway.

In the practice of the invention it will be evident that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is V 1. A horseshoe formed entirely of elastic material and composed of a body having an upwardly-extending flange around its outer edge, a toe-calk on the edge of said body connected to the periphery thereof, heel-calks on the end extremities of said body and formed integral with the under face thereof, a series flange at the edge of itsupper side, fiat-faced heel and toe calks, and intermediate pointed elastic calks having bases extending from edge 5 to edge of the body and having their points in a plane With the flat surfaces of the heel and toe calks.

In testimony whereof I affix my signature in the presence of two Witnesses.
